Description

The bilamellar tarsal rotation procedure for trichiasis: surgical procedure This man is performing bilamellar tarsal rotation on a Moroccan patient with trichiasis. This surgical procedure is mainly carried out on adults with an advanced stage of trachoma, where the eyelashes scrape the cornea. During the bilamellar tarsal rotation procedure the surgeon first fixes the eyelid, and then incises through all the layers parallel to the eyelid margin. The incision is then resutured so that the eyelid margin rotates outwards and the eyelashes are no longer in contact with the cornea. The procedure, although uncomfortable, is not painful and normally takes just 15 minutes. Surgery cannot correct existing damage but it relieves pain and prevents further damage and blindness.
